The Heidelberg DWL66+ Laser writer provides advanced patterning applications using 375 nm UV laser to pattern a single resist layer by either simple exposure, front side aligned exposure, or back side aligned exposure. In addition, the writer can generate 3D patterns by using gray scale mode in which the intensity of the laser is varied while the laser is rastered. The smallest feature size that can be printed is better than 600 nm. The resist thickness can range from 100 nm to 100 micrometer. It can also be used to make photomasks for mask based lithography system.
